REPAIR DEVICE FOR Loom-sworn) BEARINGS.

Specification of Letters Patent.

Application filed May 17,1919. Serial No. 297,803.

To all whom it may concern:

Be it known that I, WILLIAM M. PATTER- SON, a citizen of the United States of America, and a resident of Greenville, county of Greenville, and State of South Carolina, have invented certain new and useful Improvements in Repair Devices for Loom-Sword Bearings, of which the following is a full and clear specification.

This invention is designed to supply a simple repair part for the bearings of the usual bearing-pin of loom swords. These bearing-pins are usually mounted eccentrically for rotative adjustment, and the housings for the ends of the bearing-pin are cast integral with the frame. The strain is so constant and so great on these bearings that it frequently happens that the cast housings will fracture and break off. This necessitates junking the entire casting, thus entailing considerable delay due to stoppage of the loom and also the loss of the value of the casting. It is the object of my invention to supply a simple repair part which will serve as a substitute for the broken-off piece of housing, as more. fully hereinafter set forth.

In the drawings Figure 1 is a perspective view of part of a loom showing the usual form of bearingpin for the sword;

Figs. 2, 3, 4:, 5 and 6 are detail views showing the application of my invention.

In the drawings, a, designates the usual sword bearing-pin whose eccentric cylindrical end members]; and c are journaled in the usual cast housings d. This bearingpin is held in its rotative adjustments by means of set-screws e tapped down through the respective housings, the eccentric bearing 0 being provided with an annular row of holes f for the reception of the inner ends of a set-screw, to thereby positively lock the bearing-pin in its adjusted position.

In Fig. 2, the housing is shown broken,

this fracture of the housing at the point indicated being a common occurrence. This fracture invariably results in complete detachment of the to of the housing, as shown, thereby exposlng the cylindrical face of the eccentric bearing 0. When a fracture of'this sort occurs, it is customary to remove the casting from-the machine and the casting. The inner face of the bar is provided with an inclined shoulder c which bears against a shoulder j formed in' the casting. The bar lies against the side of the housing and against the end of the eccentric bearing 0, and the end of the bearing opposite the bolt h is provided with an inwardly-extending hook Zr: which is adapted to enter any one of the holes 7 in said eccentric Ibearing. When this bar 9 is thus bolted in position on the casting, with the shoulder i in engagement with the shoulder j of the casting and its hook is in eng agement with one of the holes f, the bearing- 7 pin will be rigidly held in the housings notwithstanding the fact that one of the house ings is broken away as illustrated. By'

loosening the bolt h and swinging the bar 9 thereon as a pivot, the hook ic may be released from the hole f, so that the bearingpin may be rotatively adjusted in the same manner as when it is clamped solely by the usual set-screws e.

It is desirable, in order to prevent the bar g from turning on the bolt h, to provide the same with flanges m to engage the adjacent parallel edges of the casting; and it may be further desirable to use an additional bolt 4?. for this purpose.

The nature and scope of the invention having been thus indicated and its preferred embodiment having been specifically described, what. is claimed as new is:

1. In a device of the class set forth, a casting havlng a pin journaled in housings therein, and a device for repairing one of 3. In a device of the class set forth, a casting having a pin journaled in the housings thereof, one of the journals of said pin being provided With a series of holes and one of the housings having its top notched to expose said. series of holes, and a bar adapted to be fastened to the casting at one i end and adapted at its other end to lie in said notch and engage in one of the exposed holes in the ournal pin. 10

In testimony whereof I hereunto a-ffix my signature.

WILLIAM M. PATTERSON.
